GAS BEGENERATOR.

VApplication filed August 22, 1925. Serial No. 51,727.

This invention relates to a gas regenerator and particularly to a devicewhich is adapted to effectively heat a gaseous fuel mixture prior to itsintroduction into the combustion chambers of an engine.

lt is an important object of this invention to provide a device of thekind described wherein the heating of the in-flowing. gas isinstantaneous upon starting of the engine. v

lt is a further object of this invention to provide a gas regeneratorwherein a circulation of the heating medium is due to the differentialpressures existingwithin the exhaust and intake systems of the engine.

It is another important object of this invention to provide a device ofthe class described wherein aflash heating effect is brought about.

It is another important' object of this 1nvention to provide a device ofthe class described which effects instantaneous heating of thein-flowing fuel mixture to cause immediate operation of the engine in anefficient and economical manner.

It is finally an important object of this invention to provide aninstantaneous gas regenerating apparatus of simple constructionwhichpermits of operation with low grade fuels and which facilitatesproper operation of the engine without excessive use of a choke valve orother air limiting means.

Other and further important objects of this invention will be apparentfrom the specification and the accompanying drawings.

The invention (in a preferred form) is shown onthe drawings andhereinafter more fully described.

On the drawings:

Figure l illustrates a central longitudinal section taken thru anapparatus embodying the present invention.

Figure 2 is an enlarged fragmentary detail section of the exhaust gasinlet casing.

As shown on the drawings: f

The reference numeral l indicates an intake manifold for an internalcombustion engine which may be ofany conventional construction and whichis provided ywith a depending conduit 2 which is flanged as at 3 forattachment to a carburetor or other Vaporizing device. The upper wall ofsaid intake manifold which is provided with an annular seat 4;, afords asupport for the lower portion 5 of a usual exhaust manifold 6. Theexhaust manifold is open at said lower-portion 5 and projecting thrusaid opening therein is a grooved boss 7 which opensintothe exhaustmanifold. y rlhe upper wall of the intake manifold is, provided with yathreaded opening inside said grooved boss and the lower end ofsaidthreaded opening is provided with a flange or shoulder 8 which affords asupport for an integral flange 9 formedon the upper end of a conduit l0which is of relatively thin material and which extends downwardly thruthe conduit 2 to a region of subatmospheric pressure within said conduitor in certain instances within the carburetor itself. The conduit 10maybe secured inthe position shown by the lower threaded end l1 of anapertured casing l2 which projects into the interior rof the exhaustmanifold to a desired region offrelatively high temperature. lt will beunderstood that if desired, the conduit l0 may besecured directly to thecasing l2 in any suitablemanner, the flange 9 in such cases'beingomitted.

In operation, the device of this invention reactie acts as a flash orinstantaneous heater which effectively completes the 4vaporization ofthe iii-flowing fuel mixture. Heated exhaust gases from the interior ofthe manifold 6 instantaneously flow through the apertures in the casingl2 as indicated by the arrows, flowing thence downwardly 'due to theexisting differential pressures and outwardly thru the lower end of theconduit l() into the fuel mixlture stream in the conduit 2. y This flowof heated gases thruthe conduit 10 of course serves to heat said conduitto a high temperature and brings about an instantaneousfand completevaporization of the fuel mixture in the conduit 2. f

It will be evident that by the use of this invention it is possible tobring the motor to an efficient Operating condition in a minimum timewithout the use of a choke valve or other air limiting means andconsequently an efficient and economical engine operation is assured andat the same time excessive crankcase dilution is obviated It will beapparent that the device of this invention is simple, inexpensive andeasy to install and it will be further evident to those l i skilled inthe particular art to which this invention pertains, that complete andefficient vaporization of even low grade fuel mixtures is assuredthereby. Y

Due to the fact that thek conduit 10 extends downwardly for aconsiderable-distance ported the in-flowing fuel mixture is heated at arelatively early point in its travel and conseuently distributionthereofthru the maniold is greatly enhanced.`

I am aware that numerous details of oonstruetion may be varied thru aWiderange Without departing from the principles of this invention and Itherefore do not purpose limiting the patent granted hereon otherwisethan necessitated by the prior art.`

` Y I'claim as my invention:

V1. In an internal combustion engine the' combination with -the exhaustand intake manifolds of an open ended conduit supin the intake manifoldand communivvith the exhaust manifold and an eating apertured easing inthe exhaust manifold foi1` supporting saideonduit in position andlimiting the flow of exhaust gases therethrough. In an internalcombustion engine the combination with the exhaust and intake manifoldsof an open ended conduit of relatively thin material supported in theintake manifold and communicating With the exhaust manifold and anapertured casing in gases therethrough. v

3. The combination with the exhaustk and intake manifolds of an internalcombustion engine of a flanged threaded opening in the K intakemanifold, an aperture in the Wall of the exhaustfnianifold adjacent saidthreaded opening, a Conduit extending into the intake manifold having aiiange at one end thereof seated on the flange at said opening and anapertured threaded Casing engaging said threaded opening and saidflangeonthe oonduit for securing the conduit in position and permittingy avlimited flow ofvheated exhaust gasesthru said Conduit.

In testimony whereof I have hereunto'subscribed my name.
